It was a blast. There were lots of teens on the ride as well. We also met a 12 year old that zoomed up Mt. Tabor. He told us he wanted to be the youngest Tour de France winner!
If you're that close to Bloomington, you might consider a trip with this group:

I'd like it if SilverSon would do this trip (he's 14). I think it looks like a blast!
Maybe you can encourage him to at least make sure he's ready for the Hilly next year!
